SERCEFLYER,
The enclosed is from The Little Dragon redrawn in Cad and then converted to a PDF file. The file calls for a washer to be tapped #8-32. My personal opinion is that this prop drive washer would not last very long at 1/16" thick -- easy to strip threads. Also agree that by threading the drive shaft all the way acts as a stress riser.
